www.domain.com works domain.com does not

Hello,

We are having a problem with our website. When on the inside of our
firewall www.domain.com takes users to our site, but domain.com takes
them to a default IIS under construction message. Outside of our
firewall the www.domain.com works just fine, but domain.com can't be
found.

Thanks,

Matt

Hello,

Inside your firewall, does www.domain.com and domain.com resolve to the
very same IP?

Did you set the SOA record in your DNS correctly so that the associated A
address is the same as that used for the www. host? Did you add both
www.domain.com and domain.com as host headers on your site? (sounds like
domain.com isn't, so shows the Default Web Site rather than the one you
expect to see).

Ok, the issue on the outside has been resolved our ISP takes care of
that. However There are multiple entries in internal DNS that are (same
as parent folder) that by default point to domain.com com which is also
the name of our active directory domain name. I delete those entries I
also changes the SOA value accordingly. This fixes everything but the
values always revert to their original setting after several hours. Why
does this keep happening?

Thanks,

Sounds like either your ADS is overwriting your DNS changes, or the DNS
you're changing is no longer being used and your PC is looking at a
secondary instead - have you got multiple DNS servers all running as
primaries, instead of one primary (the one you changed) and the rest
secondaries pulling from it? If you've got secondaries configured correctly,
are the changes being propagated to them?

We do not have secondaries running. How do I prevent ADS from
overwriting DNS changes?

Thanks,

You don't use an internal and external zone with the same name. And
you don't run your external zone as an AD integrated zone.

Try the DNS groups and look for "split brain" or "split horizon" DNS
(or Google it) and you'll see what you're facing.
